Note: Befoe you start, make sure all of your ingredients are cold (except the chocolate bar), if you want the ice cream to set to serving consistency.

Add milk, cream, cinnamon, sugar, and vanilla into your ice cream maker. When the ice cream begins to firm up, add the shaved chocolate,so it distributes evenly. Wait until the ice cream maker is done, put the ice cream in a container, and return it to your freezer until it is hard enough – which, depending on your ice cream maker, should be approximately 2-4 hours (minimum).
